[0002] In industrial production, jigs are important tools used to assist in positioning, clamping, and installing workpieces, and are widely used in various processing, inspection, and assembly processes. Existing jig fixing methods usually rely on mechanical structures, such as bolt tightening, manual locking, or pneumatic control, but these still have many shortcomings in practical use.

[0003] The existing fixtures have poor adaptability in their fixing structure, making it difficult to position and fix the workpiece. On the other hand, the fixing efficiency is low, usually requiring multiple manual adjustments or the use of tools, which consumes operation time and is not conducive to improving production efficiency. In addition, due to the low stability of the fixing structure during use, it may loosen or shift during processing, affecting processing accuracy and product quality. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic fixing fixture that solves the problem that existing fixtures cannot stably position and fix workpieces, thus reducing production efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution: A magnetic fixing fixture includes: a fixture plate, a positioning component, a transmission component, and an auxiliary component. The positioning component is disposed at the top of the fixture plate and is used to position a workpiece to be processed on the fixture plate. One end of the positioning component is rotatably connected to the transmission component, which is used to convert translation into rotation. One end of the transmission component is rotatably connected to the auxiliary component, which is used to press and fix the workpiece to be processed. The positioning component includes a sliding part and an adjusting part. The bottom end of the sliding part is slidably connected to the fixture plate, and the adjusting part is provided on the side of the sliding part. The sliding part is used to slide and position the size of the workpiece to be processed, and the adjusting part is used to adjust the size of the workpiece by compression. Preferably, the sliding part includes a sliding plate and a positioning plate, the top of the fixture plate is provided with a sliding groove, the inside of the sliding groove is slidably connected to the sliding plate, and the top of the sliding plate is fixedly connected to the positioning plate.

[0014] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0015] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] refer to Figure 1 - Figure 2 As shown, this utility model embodiment provides a magnetic fixing fixture, including: a fixture plate 1, a positioning component 2, a transmission component 3, and an auxiliary component 4. The positioning component 2 is disposed at the top of the fixture plate 1 and is used to position the workpiece to be processed on the fixture plate 1. One end of the positioning component 2 is rotatably connected to the transmission component 3, and the transmission component 3 is used to convert translation into rotation. One end of the transmission component 3 is rotatably connected to the auxiliary component 4. The auxiliary component 4 is used to press and fix the workpiece to be processed.

[0018] The positioning component 2 includes a sliding part 210 and an adjusting part 220. The bottom end of the sliding part 210 is slidably connected to the fixture plate 1, and the adjusting part 220 is provided on the side of the sliding part 210. The sliding part 210 is used to slide and position the size of the workpiece to be processed, and the adjusting part 220 is used to adjust the size by squeezing according to the size of the workpiece to be processed. The sliding part 210 includes a sliding plate 211 and a positioning plate 212. The top of the fixture plate 1 is provided with a sliding groove, which is slidably connected to the sliding plate 211. The top of the sliding plate 211 is fixedly connected to the positioning plate 212.

[0019] During use, the workpiece is manually placed onto the fixture plate 1 from the side, so that the workpiece squeezes the positioning plate 212 by its size, causing the positioning plate 212 to drive the sliding plate 211 to slide on the fixture plate 1. When the workpiece stops squeezing the positioning plate 212 and driving the sliding plate 211 to slide, the position of the positioning plate 212 is the positioning position.

[0020] refer to Figure 1 and Figure 2 As shown, the adjustment part 220 includes: a first adjustment plate 221, a second adjustment plate 222 and a slide rail 223. The slide rail 223 passes through the interior of the positioning plate 212. The interior of the slide rail 223 is slidably connected to the first adjustment plate 221 and the second adjustment plate 222 respectively. The positioning plate 212 is fixedly connected to the first adjustment plate 221 and the second adjustment plate 222 with springs 224 respectively.

[0021] When the workpiece presses against the positioning plate 212, the workpiece presses against and pushes the first adjusting plate 221 and the second adjusting plate 222, causing the first adjusting plate 221 and the second adjusting plate 222 to simultaneously press against the spring 224 and push the positioning plate 212. This causes the positioning plate 212 to drive the sliding plate 211 to slide on the fixture plate 1, thereby causing the first adjusting plate 221 and the second adjusting plate to slide within the slide rail 223. The difference is that the first adjusting plate 221 slides along the first direction within the slide rail 223, while the second adjusting plate 222 slides in the second direction within the slide rail 223. The first direction and the second direction are opposite, causing the first adjusting plate 221 and the second adjusting plate 222 to begin to move away from each other.

[0022] refer to Figure 1 and Figure 2As shown, the transmission assembly 3 includes: a first rotating plate 301, a second rotating plate 302, a third rotating plate 304, a fourth rotating plate 305, and a connecting plate 303. The bottom ends of the first adjusting plate 221 and the second adjusting plate 222 are respectively rotatably connected to the first rotating plate 301 and the second rotating plate 302. One end of the first rotating plate 301 and the third rotating plate 304 are rotatably connected, and one end of the second rotating plate 302 and the fourth rotating plate 305 are rotatably connected. The junction of the third rotating plate 304 and the fourth rotating plate 305 is fixedly connected to the connecting plate 303.

[0023] When the first adjusting plate 221 moves along the first direction within the slide rail 223, it drives the first rotating plate 301 to move. When the first rotating plate 301 moves to the first position, it pulls the third rotating plate 304 to rotate counterclockwise. At the same time, the second adjusting plate 222 moves along the second direction within the slide rail 223, causing the second adjusting plate 222 to drive the second rotating plate to move along the second direction. The second rotating plate 302 drives the fourth rotating plate 305 to rotate clockwise, thereby causing the third rotating plate 304 and the fourth rotating plate 305 to drive the connecting plate 303 to move downward, so that the connecting plate 303 synchronously drives the auxiliary component 4 to move downward.

[0024] refer to Figure 1 and Figure 2 As shown, the auxiliary component 4 includes: a fixing frame 401, a clamping plate 402, and an electromagnet 403. The fixing frame 401 is fixedly connected to the side of the fixture plate 1, and the inside of the fixing frame 401 is slidably connected to the clamping plate 402. Electromagnets 403 are arranged around the clamping plate 402. Existing fixing methods such as screw clamping and pneumatic clamping can only achieve fixing in a single direction or a single form, and the fixing effect is unstable. In this embodiment, electromagnets 403 are arranged around the clamping plate 402, and the clamping plate 402 can slide inside the fixing frame 401. Each structural unit (such as the clamping plate 402, electromagnets 403, and sliding connection) has a clear division of labor. From the placement of the workpiece to its positioning, the workpiece is then pressed down and electromagnetically attracted, forming an automatic linkage that works together to effectively prevent workpiece displacement or loosening and greatly improves processing accuracy.

[0025] When the connecting plate 303 drives the auxiliary component 4 to slide downward, the connecting plate 303 drives the pressing plate 402 to slide downward within the fixed frame 401, causing the pressing plate 402 to drive the electromagnet 403 to move downward. Since the electromagnet 403 is energized by an external switch, when the pressing plate 402 drives the electromagnet 403 to press and fix the workpiece to be processed, the external switch can be manually turned on to energize the electromagnet 403, causing the electromagnet 403 to generate magnetic force. Then, the electromagnet 403, together with the pressing plate 402, will adsorb and fix the workpiece to be processed on the fixture plate 1.

[0026] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
